IMPROVEMENT IN HAND-SPINNING MACHINE.

TO ALL IT MAY CONCERN:

Be it known that 1, JAMES M. HART, of Des Moines, in the county of Polk,and State of Iowa, have invented a new and improved Hand-SpinningMachine; and I do'hereby declare that -the following is a full, clear,and exact description thereof,-which will enable othersskilled in theart to make and use the same, reference'heing had to the accompanyingdrawings, forming part of this specification, in which-- Figure 1 is aplan or top View of my improved hand-spinning machine.

Figure 2 is a front elevation of the same.

Figure 3 is an end view, with part of the framing broken out to show theinterior parts.

Similar letters of reference indicate like parts.

This invention relates to a new and useful improvement in theconstruction of a machine for spinning wool or cotton yarns or threads,the object of which is to spin by hand a number of threads at a timeinstead of a single thread, as with the common domestic spinning-wheel.It consists in an arrangement of driving-pulleys or drums, worked by acrank connected by a self-acting clutch with feeding-rolls which are soarranged and operated as to move to and from a setof spindles for thepurpose of supplying the fibre to be spun, and allowing the thread to bewound upon the spindle, the operationbeing similar in principle to thatof the mule in spinning with machinery actuated by steam or other power.The machine is simple and easily managed, and for domestic use will bemuch more useful than the common spinningavheel, as one person can domuch more work with it in the same time. p

A represents a strong square orrectangular frame, for supporting themachinery. On one side of the frame is a set of spindles, a a,arrangedin the ordinary manner on a cop-rail, B, stepped at the foot ina side rail, 0, and connected by bands, I; b, with driving-pulleys ordrums, M M, made fast on a horizontal shaft, e, upon one end of whichshaft is a crank, D. On the top of the frame A is placed a slidingcarriage, E, which travels in grooves made on the inside of the twoopposite toprails F F, and upon this sliding carriage E are mounted twohorizontalfeed-rolls d d, placed one over the other. The top feed-roll01 carries a pin-ion, c, on the end of a short shaft projecting throughone side of the travelling carriage E, which pinion works in a flat,

straight rack, e, that is supported-on spiral springs g g lengthwise onone of the top rails F, and held in place by guide-pins h 7!. at theends. Between the drums or driving-pulleys M M, a ratchet-clutch, G, isset upon the crank-shaft c to connect with one of the drums, and rotatewhen the shaft is turned in one direction, and wind up a band, 7:,upon areel forming a part of the clutch, and thus operate the travellingcarriage E, to which it is attached, as hereinafter explained. Connectedwith the clutch G is a shifting-bar or lever, H, fig. 3, for throwing itin and out of gear. The lever H is made fast, in or near its middle, tothe top of a centre post, H, which works the clutch G when it turns bymeans of an arm, H the end of which arm moves in a grooved wheel, m, onthe outside of the clutch, and thus shifts it back and forth on theshaft 0 to throw it in and out of gear. The lever- H is also madecurved, or in the form of a bow, as shown in fig. 1, so that the endsprojecting inward shall come in contact with a fixed pendent piece, I,attached to the travelling carriage E, when it approaches the limit-ofits movement in both directions, by which means the lever His operatedto throw the clutch G in and out of gear at theright moment in theoperation of spinning. i

In the operation of this machine for spinning, when the carriage E isplaced forward on the side next the spindles a a, and the clutch G is ingear with the drum M, by turning the crank D and revolving the drums MM, motion will be given to the spindles, and.at the same time thecarriage E will travel away from the spindles, being drawn by the bandIt as it is wound upon the reel on the clutch G. So soon as the carriageE begins its movement away from the spindles a a, the pinion e engagesin the rack e, and turns the upper feed roll 11 as the carriage travelsback, until it reaches its opposite limit, when the pendant I strikesthe lever H, and throws the clutch G out'of gear. The'carriage E thenruns forward to the front again by means of a weight attached to a cord,as indicated in red, fig. 3. When the carriage E moves back from thespindles, the foodroll at turns, as stated, and, operating by frictionon the lower food-roll d, the wool, or other material to be spun, isdelivered by the rolls to form the yarn as they rotate and recede withthe carriage from the spindles which twist it. The rack e is in gearwith the pinion e, and the rolls d d revolve only when the carriage Emoves away from the spindles. The rackis held down, so that the pinioncannot engage in it when the carriage moves forward towards thespindles, by means of a pivoted pendent, s, on the side of the carriageE, which then catches against a pin, n, and hangs vertically, so as tobear upon the top of the rack, and depresses it against the spiralsprings gg, but the rack rises the moment the carriage moves away fromthe spindles, as then the pendent s is thrown up against another pin, n,and the rack rises by the action of the springs gg, thus engaging thepinion e in the rack. Back of the spindles a a is a rod or bar, 1) 10,extending across the frame A on a level with the ends of the spindlesand the line of junction of the rolls d d, for supporting the threads asthey are spun; and suspended to an axis, q q, in front of the spindles,is a vibrating r od, 1'7, also extending across the frame and betweenthe supporting rod 1) p and the spindles, for the purpose of depressingthe threads-and winding them on the cops, while the carriage E isreturning to the front of the machine.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. The arrangement of the clutch G, driving pulley or drum M,shifting-lever H, pendent piece I, the band K, and the carriage E,operating substantially as and for the purpose herein described.

2. The spring rack e and pinion e, in combination with the feed-rolls dd, the carriage E, the clutch G. and the shifting-lever H, arranged andoperating substantially as and for the purposes herein described.
